Strange Haunted/Devoted Modifier Node behaviour

Hi!

Eversince the start of the league the Necropolis Atlas nodes in the bottom left of the tree have been behaving strangely.

Eversince the newest update today, most of the nodes started working correctly. So I redid all of my testing and am left with one last case where I can't explain why the effects on the map are the way that they are.



In my examples, all of the cases behave as you would expect to, except the last one.

Why did the haunted modifiers (increased global accuracy rating for example) get downgraded and then buffed from what was shown in the pre-map Lantern UI?

From what I can read on the nodes in the tree, what should happen is this:

Haunted Mods Tier +1
Haunted Mods Effect +20%

Instead, what it looks like is this happened:

Haunted Mods Tier -1
Haunted Mods Effect +20%

Is this a bug or am I just misunderstanding something?

Thank you in advance.
